Formula breakdown
Formula
bricks = area ÷ ((L + joint) × (H + joint)), plus waste= 12

Simplified model: results are quantity estimates only. They ignore openings, overlaps, cuts, site conditions and local building codes. Structural figures are not a substitute for a design by a qualified engineer.

How is the number of bricks for a wall calculated?+
The calculator divides the wall's area by the area one brick occupies including its mortar joint (brick face dimensions plus typical joint width), which for a standard modular brick with 3/8 in joints works out to roughly 6.5-7 bricks per square foot.
Why does joint thickness affect brick count, not just mortar volume?+
Thicker mortar joints mean each brick effectively takes up more wall space, so fewer bricks are needed to cover the same area — a wall built with 1/2 in joints needs measurably fewer bricks than one with 3/8 in joints, even though the bricks themselves are identical size.
Should I add a waste percentage to the brick count?+
Yes, typically 5-10% to cover breakage, cuts at corners and openings, and color-matching flexibility for future repairs. Ordering exactly the calculated count often leaves no margin for the inevitable broken or miscut bricks on a real job site.
Does the calculator account for openings like windows and doors?+
The basic wall area calculation assumes a solid wall; you should subtract the area of windows, doors, and other openings from the total wall area before running the brick count, since those spaces need no brick (aside from minor cuts at the edges).
Why do different brick sizes (standard, modular, Roman, Norman) give very different counts for the same wall?+
Brick count is inversely proportional to the face area of a single brick plus its joint, so a larger format brick like a Norman brick covers more wall area per unit and needs significantly fewer bricks than a standard modular brick for an identical wall size.
